KINK-BREVENTER FOR SILK-SPINNING MACHINERYQ EPECIFICATION forming part of Letters Patent No. 350,345, dated October 5, 1886. Application filed June Ill, 1884. Serial No. 133,073. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH A. CHAPMAN, of

. the city of Norwich, county of New London, and State of Connecticut, have invented a certain new and useful Improvement in Kink-Preventers for Silk-Spinning Machinery, which improvement is fully set forth and described in' the following specification, reference being bad to the drawings which form a part of and accompany this specification.

My improvement consists in. a certain device which, when attached to silk-spinning or doubling and twisting maehirery as commonly constructed, will effectually prevent 1 the kinking of the strand of silk while said machinery is stopped, my immediate object being' to provide a device which shall be cheaply constructed and easily applied to spinningframesnow in use.

There has been much trouble experienced heretofore by the kinking of the strand of silk which remains exposed between the deliveryspool and the upper or receiving spool while the machineryis stopped or in the act of stopping, (as at the close of a days work or duringthe noon hour,) and a considerable length of time must be spent each day-in straightening such kinked portions before the machinery canbe started. In straightening those strands which are kinked many of themare broken and must be knotted, thus reducing the quality and value of the work produced. My device is intended to overcome this serious difficulty, and to hold each thread at a uniform and constant tension while the machine is stopped.

Briefly stated, my invention consists, first, of a ring of plush or similar material, which surroundsiand engages the upper flange of the delivery-spool, and, second, of mechanism for raising, lowering,and locking said device, as

hereinafter fully described;

In the accompanying drawings, Figure 1 is *3. transverse sectional view of the principal parts of a double or two-sided spinning-frame,

showing my new device properly applied. Fig. 2is a top view of a section of the bolsterrail A, showing three spools with my new attachment applied. Fig. 3 is a detached view, somewhat enlarged, of one of my kink-pie venters- Fig. 4 is a view of Fig. 3 from the back or inner side of the frame, showing the means employed to seen re the piece I) adjustably to the rail 6. Fig. 5 is a cross-section on line a m, Fig. 4. Fig. 6 is a detached view of one of the lever-arms (1' of Fig. 1.

Iii the annexed drawings, the letter A represents the upper or bolster rail, B the step or lower rail of a silk-spinning frame, and C .slides, vertically, rod-b, the downward move ment of said rod being limited bythc stoppins (Z, or, it'preferred, bya collar secured adjustably to said rod, as shown. at 12. Two or more of the vertical rods 1) should be used on 7 each side of a frame.

Secured to and moving with thenpperend of rod b is a rail, 0, extending the entire length of theframc. Attached to this rail care my devices for overcoming the tendency to kink, one for each spindle. Said devices are made, preferably, of wood or other light and cheap material, and substantially of the form shown at l) in Figs. 2 and 3-that is to say, they are each provided with a central circular opening, 8 5 which, when in place and properly adjusted, may slip down over the heads of the spools E, a narrow annular space being left between the flange of the spool and the inner wall of the jvooden piece- 1). This space I fill by glu- 9 ingor otherwise fastening to piece D a ring of soft or yielding material, preferably of plush, (see It, Fig. 3,) the nap on said plush engaging and restinglightly on the periphery of the spool-flange. The rail 0 and pieces D'95 are lowered to the position shown in Fig. 1 after the machineis set in motion and remain in said .lowered position below the lower flanges of the spools until it again becomes necessary to stop the machine, when said raa'lis elevated to the position indicated by the dotted lines in Fig. 1, and the spindles are then stoppedin the usual way. When the pieces D are raised to a level with the upper flanges of spools E, the Slil'illld'i whirls around with said spool within the ring of plush, displacing the nap, which acts as a continuous series of minute springs, each one of which, as strand '5 passes it, snaps back to its place ready for said strand when it makes its next round. When the spool E is'stopped, these minute springs retain said strand in a taut condition, instead of allowing it to slacken and kink, as it .is inclined to do when it is not so supported. Thering of plush could, if so desired, be allowed to remain at all times in its elevated position and work fairly well; but as I find it more convenient to remove the spools from the spindles when said ring is lowered out of the way,I have arranged my device with the vertical movement, as described.

Among the many materials which could be used (instead of plush) with very good results may be mentioned rubber, leather, velvet, woolen and worsted goods; but I find by actual experiments that plush gives the most satisfactory results, and therefore prefer to.

use it.

Having thusdcseribed the device by which I prevent the kinking of the thread of silk, I-

willproceed to describe the mechanism which I employ to move said device. It will be evident that each of the rails 0 could be raised and lowered independent of the other rail or rails of the same frame; but in order to save time I have so connected said rails with each other that they work in unison-that is to say, when one of saidrails is caused to move, all of the rails c of the same frame movcat the same instant and in the same direction. Secured to the floor underneath the frame proper is a frame,K,having bearings in which are located rock-shafts 7.: 7.2, extending the entire length of the machine, and so connected by gears or segments of gears m at each end that a movement of one shaft will impart motion (in the opposite direction) to the other shaft. Secured to shaft 7: is a lover, at, whose longer arm passes over shaft 7;, reaching to a point nearly underneath the vertical rod 1), it being connected with said rod 7) by a pitman, o. The shorter arm of lever it extends downward, as indicated by dotted lines in Fig. '1, and also shown in the detached view ,liig. t3. Shaft It has secured to it a similar lever, 1 whose longer arm reaches across shaft Ir, and whose shorter arm is connected to the short arm of lever n by a stiff spring, 8, the constant tendency of said spring 8 being to bring the short arms together, and, in consequence, to. carry the longer arms of said levers (and such parts as are connected with them) upward.

To hold the kink-preventing devices below the spools E while the machinery is in operat1on,I zawe rov-ii, da spring-latch, t, secured to the bolster-rail A. Said latch, as piecesD are forced downward,clasps one of said pieces, (as shown in Fig.'1;) or, if preferred,said spring could be arranged to clasp the rail 6.

In Fig. 1 I have shown latches it applied to both'sides of the frame; but in practice I use said latchon but one side, so that when the latch is withdrawn the kink-preventers on both lines of spindles are immediately thrown up into place on a level with the upper flanges of spools E, as above described.

Having thus described my invention, I cla1m- 1. In combination wi'ththespindlc andspool ot' a spinning-frame, a ring of'p'lush' or other yielding material arranged to entirely surround and engage lightly the flange at the, delivery end of said. spool, the strand of silk passing upward between the plush and said spool, all substantially as and for the purpose specified.

2. In combinati of a winnin 1'. .e, aring of plush'or other yielding material arranged to entirely surroundand engage the flange at the delivery end of the spool, and means, substantially as described, for elevating and depressing the on with the spindle and'spool ring of yielding material, all substantially as r set forth.

8. In combination with thespindle and spool of a spinning-frame, a ring o'fplush orother yielding material, the rail 0, the rods I), supporting the latter, and means, substantially as described, for automatically forcing the rods upwardly, substantially as set forth.

i. The combination, with the spindle and spool of a spinning-frame, of vertically-movable rods, a rail supported at the upper ends thereof, pieces attached to the rail and having openings, rings of plush or like material in i said openings, means, substantially'as 'described, for elevating and depressing said rings, and a spring-latch, substantially as set forth.
